Referring :fn-st to Figure 1,there is A"shown by way o'f example a multiple 4outlet 'xture having'water supplied through pipe 10 either'to'the showerh'ead 12 or lto a foot spray 14. A diverter :16 may be utilized -to divert 4all the waterout the showerhead when itlisfopened. The showerhead utilized in this Xture, illustrated in Figures 52, 3 and 4, is moved to fthe' open position permitting 'How of water therefrom where the showehead is held open by When water ow is lterminated 'the showerhead closes. if water vflow is again commenced through pipe Il) it is diverted through foot sprayl and cannot discharge through showerhead 12 until same is again opened.

It is apparent that a vself closing valve of this type has many applications vsuch as for example'in a shampoo valve `as illustrated in Figures through 13. This shampoo valve is normally attached upon a exible hose and connected with a wash basin 'to a common water supply.

Describing first the shampoo valve, water .-is delivered to the valve 18 through :tube 20 which is screwed into Ithe bonnetZZ which in turn threadably receives spray body 24.

The sho'werhead has a stepped restricted throat 98 therein with a deecting member 100 supported in the throat. The dellecting member has a shoulder 102 formed thereon so that water owing through the showerhead strikes shoulder 102 and is deliected against skirt 104 and discharged in a suitable conical shower.

While what hereinbefore has been described is the preferred embodiment of this invention, it is readily apparent that alterations and modifications can be resorted to without departing from the scope Vof this invention and such alterations and modications are intended to be within the scope of the appended claims.
